记述一下步骤以备查。
准备工作：
需要把Jakarta Commons FileUpload及Jakarta Commons io的包放lib里。
我这边的包是：
commons-fileupload-1.1.1.jar
commons-io-1.3.2.jar
然后在spring-servlet.xml进行multipartResolver配置，不配置好上传会不好用。
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"><value>100000</value></property> <property name="defaultEncoding"><value>UTF-8</value></property> </bean>
接下来就是页面了：
注意Form的写法和文件上传组件的写法。
<form action="uploadPosdetailFile.html" method="post" ENCTYPE="multipart/form-data"> <div class="form" > <p> <span class="req"><input id="startDateTxt" name="startDateTxt" class="field size4" title="Enter the date" /></span> <label>Start Date: <span>(Date format:MM/dd/yyyy,eg:01/01/2014)</span></label> </p> <p> <span class="req"><input id="endDateTxt" name="endDateTxt" class="field size4" title="Enter the date" /></span> <label>End Date: <span>(Date format:MM/dd/yyyy,eg:12/25/2014)</span></label> </p> <p> <span class="req"><input type="file" name="uploadFileCtrl" class="field size4" title="Choose the file" /></span> <label>Upload file: <span>(click browse to choose)</span></label> </p> </div> <div class="buttons"> <input id="queryBtn" type="Submit" class="button" value="Submit" /> </div> </form>
再在控制器里写处理代码，注意参数和页面控件的对应关系：
@RequestMapping(value="/uploadPosdetailFile")
public String uploadPosdetailFile(@RequestParam("startDateTxt") String startDateTxt,
@RequestParam("endDateTxt") String endDateTxt,
@RequestParam("uploadFileCtrl") MultipartFile file,HttpServletRequest request,HttpServletResponse response){
try {
System.out.println("@@@@@@@@@1.startDateTxt="+startDateTxt);
System.out.println("@@@@@@@@@2.endDateTxt="+endDateTxt);
System.out.println("@@@@@@@@@3.file="+file.getOriginalFilename());// 得到上传文件的文件名
if(file.isEmpty()==false){
InputStream is=file.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br=new BufferedReader(isr);
String s;
while((s=br.readLine())!=null ){
System.out.println(s);
}
br.close();
isr.close();
is.close();
}
return "/pages/posdetail/uploadposdetailresult/index.jsp";
} catch (Exception e) {
e.printStackTrace();
logger.error(e);
request.setAttribute("error", e.getClass());
request.setAttribute("reason", e.getMessage());
StackTraceElement[] arr=e.getStackTrace();
request.setAttribute("stackTraceElements", arr);
return "pages/error/index.jsp";
}
}
